The Cost structure is used in Menus and Products. The customer is able to specify four types of costs:

1. PRICE: A simple price, optionally "per" something. (e.g., price = 9.00, unit = per pound)
2. RANGE: A price range, optionally "per" something. (e.g., price = 9.00, rangeTo = 12.50, unit = each)
3. NONE: No price specified.
4. OTHER: Allows the user to enter text. (e.g., other = Call for price)

Seperately, the customer is able to specify options on the Cost. For example:

1. A Pizza sold in 3 sizes:

   
   [{"Small", "9.00"}, {"Medium", "11.00"}, {"Large", "13.00"}]
   

2. Extra toppings on a sandwich:

   
   [{"Bacon", "1.00"}, {"Avocado", "2.00"}]
   

Example Cost Substructure:

{
  "type": "PRICE",
  "price": "9.50",
  "unit": "Per Sandwich",
  "rangeTo": "",
  "other": "",
  "options": [
    {"name": "Bacon", "price": "1.00", "calorie": 150},
    {"name": "Avocado", "price": "2.00", "calorie": 60}
  ]
}

The Calories structure is used in Menus only. You are able to display calories in two ways:

1. FIXED: A simple calorie count (e.g., calorie = 250)
2. RANGE: A calorie count range (e.g., calorie = 250, rangeTo = 500)

Example Calorie Substructure:

{
  "type": "RANGE",
  "calorie": 250,
  "rangeTo": 500
}
